Parsing XML with XmlListModel

filipdns

Hello,

I need to parse XML like:

<response version="1.2" xsi:noNamespaceSchemaLocation="http://aviationweather.gov/adds/schema/taf1_2.xsd">
<request_index>19865992</request_index>
<data_source name="tafs"/>
<request type="retrieve"/>
<errors/><warnings/>
<time_taken_ms>8</time_taken_ms>
<data num_results="1">
<TAF><raw_text>TAF LFAT 220800Z 2209/2218 VRB02KT 9999 SCT020 PROB30 2209/2211 BKN010
</raw_text>
             <station_id>LFAT</station_id>
             <issue_time>2019-10-22T08:00:00Z</issue_time>
             <bulletin_time>2019-10-22T08:00:00Z</bulletin_time>
             <valid_time_from>2019-10-22T09:00:00Z</valid_time_from>
             <valid_time_to>2019-10-22T18:00:00Z</valid_time_to>
             <latitude>50.52</latitude>
             <longitude>1.62</longitude>
             <elevation_m>14.0</elevation_m>
             <forecast>
                              <fcst_time_from>2019-10-22T09:00:00Z</fcst_time_from>
                              <fcst_time_to>2019-10-22T18:00:00Z</fcst_time_to>
                              <wind_dir_degrees>0</wind_dir_degrees>
                              <wind_speed_kt>2</wind_speed_kt>
                              <visibility_statute_mi>6.21</visibility_statute_mi>
                              <sky_condition sky_cover="SCT" cloud_base_ft_agl="2000"/>
</forecast>
TAF>
</data>
</response>

with QML code below:

    XmlListModel {
        id: xmlModel
        source:""
        query: "/response/data/TAF"
        XmlRole { name: "station_id"; query: "station_id/string()" }
        XmlRole { name: "fcst_time_from"; query: "forecast[1]/fcst_time_from/string()" }
        XmlRole { name: "fcst_time_to"; query: "forecast[1]/fcst_time_to/string()" }
        XmlRole { name: "wind_dir_degrees"; query: "forecast[1]/wind_dir_degrees/string()" }
        XmlRole { name: "wind_speed_kt"; query: "forecast[1]/wind_speed_kt/string()" }
        XmlRole { name: "visibility_statute_mi"; query: "forecast[1]/visibility_statute_mi/string()" }
        XmlRole { name: "sky_condition"; query: "forecast[1]/sky_condition/string()"  }
    }

I read correctly all data except "sky_condition" because the beacon is not the same as other.

How should I decode <sky_condition sky_cover="SCT" cloud_base_ft_agl="2000"/> compare <visibility_statute_mi>6.21</visibility_statute_mi> ?

thank you very much for your help

@filipdns I found solution myself:

XmlRole { name: "sky_condition"; query: "forecast[1]/sky_condition/@sky_cover/string()" }

thank you very much ;-)
